From 331e06bbde5856059b7a6bb183f12878ed4decb1 Mon Sep 17 00:00:00 2001 From: Zhen Lei Date: Wed, 7 Jul 2021 09:45:17 +0200 Subject: [PATCH] media: venus: hfi: fix return value check in sys_get_prop_image_version() In case of error, the function qcom_smem_get() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
